JOSEPH NIXON, OF PITTSBURG, PENNSYLVANIA.

IMPROVEMENT IN EJ ECTO RS.

Specification forming pai-t ot' Letters Patent No. 104,986, dated Jul 5, 1870.

To all 'whom it may concern:

Be it known that I, J osEPH NIXoN, of the city of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Steam -Hydropult; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing, making part of this specification, in whichp Figure l is a side'elevation of my improved hydropult; and Fig. 2 is a sectional view of the same without the bottom, showing the position of the injection-pipe anddiaphragm.

Like letters ot1 reference indicate like parts in each.

My invention relates to that class of water pumps or elevators which are operated by the continuous injection into the pump of steam 5 and consists in such an arrangement in the receiver of a steam injection-pipe and a diaphragm having an opening extended across at or near the discharging end ofthe receiver that the steam from the injection-pipe shall be discharged in front of and pass through the opening in the diaphragm, forcing the water along with it.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and use.

In the drawing, a represents the receivingvessel, open at the bottom, and having a dischargingopenin g, a', at the other end.

Across or a little below the opening c is a diaphragm, b, in the center of which there is a small opening, b.

Entering the receiver a, at any convenient point, is a steam injection-pipe, c, whose discharging end is in the inside, just opposite the opening b in the diaphragm b.

In making use of my improved hydropult, the lower end of the vessel a is placed in the water, and steam is injected through the pipe c into the vessel (t and out of the opening b'.

low, which also is forced through the opening.

b and out the discharging end a', and up a discharging-pipe attached thereto to thede` sired elevation.

If, however, as in case of pumping bilgewater from boats, it is desired to have the reservoir a out of the water, I close the open lower end by any suitable bottom, d, and make the joint between the two air-tight. From this bottom, leading to the water, I make an induction-pipe, e. This extended arrangement is operated in manner described..

To secure and steady the whole, I make a iiat stand, f, which is fastened to the deck by screws, bolts, 85e.

My improved hydropult is simple and cheap in its construction and operation, and has been found to elevate water to a greater height than those heretofore in use, or elevate it to an equal height with a less pressure of steam. It'

is operated by steam at ordinary boiler-pressure.

Having thus described my improvement, what I claim as my invention, and desire to secure by Letters Patent, is-

A hydropult or ejector consisting ot an open or hollow chamber, a, closed at the discharging end by a diaphragm, b, except at the discharging-orifice b', a short distance below the injection side ot' which orifice is presented the discharging-oriticeot a steam-pipe, all constructed and arranged substantially as shown and described. v

In testimony whereof I, the said J osEri-I NIKON, have hereunto ,set my hand.
